Yes, LCD monitor.  Here's the back.

I'm using the default config.txt, I don't see high or low set.   I'm guessing that means default = high?  Config attached as PDF below. 

I could use some help with my setup and resolution in-game.  Here's my scenario.

• Originally used an Arpicade Pi 3, recently moved to a PI 5 and downloaded 5 v2.7
• Boots great, launch screen looks perfect and 4 player works great.  My cabinet is primarily focused on NHL Open Ice 2 on 2. 
• In game, the visuals get squashed.  I have tried every HDMI mode.
• Running the ROM with MAME .275.
• Screenshot attached.

Any suggestions? 

I will need to look into it, what type of monitor are you using?  It looks like it may be a LCD in the picture?  Are you in high res mode?

Switching low res to high res can be done by creating an empty text file callled 'highres.txt' in the boot partition and running the system on a Pi, it will turn off automatically when the system is setup.  Switching from high res back to low res is similarly done with 'lowres.txt'.

Switching low res to high res can be done by creating an empty text file callled 'highres.txt' in the boot partition and running the system on a Pi, it will turn off automatically when the system is setup.  Switching from high res back to low res is similarly done with 'lowres.txt'.

Low res was the same result. 

High res was sharper text still squished vertically. 

Next steps?

could you please post a photo of the squash in highres mode (or was it the same as the first photo?)  In game shouldn't be squashing in highres, but maybe I've missed something.

This is high res.  The color looks off too. 

That looks like it is running in low res, like it's putting a 240p image on a 480p screen, not sure why.

I just tested myself on ARpiCADE_5 v2.8 set to highres mode and it was normal looking (I had the rom in MAME0.274 but it should be the same).  There shouldn't be any difference for highres with 2.7, are you certain you set highres mode correctly?  If you made any changes to config.txt you might need to change them back to the default.  I'm not sure what is causing the issue for you assuming you have set high res correctly.

I made the highres.txt file in the boot partition.  It booted up and then powered off.  I powered it back on and went back into the game and got that screen.   The highres.txt file was no longer in the boot partition when I looked at the files. 

I uploaded my config.txt file as a PDF on the last page. 

EDIT: Just did it again with the same results. 

sounds like you did it all right, not sure whats happening...  it maybe worth downloading 2.8 and trying that as it worked when I tried it.

Tried MAME 0.279 as well but I can't replicate this...  What is the filename of the rom you're using?  Maybe I was trying a different revision or something.

I've tried it in multiple MAME versions with the same results.  I'm using whatever Open Ice version came with the the Arpicade 3.  I think it's 1.21 but I'm away from my machine at the moment.   I really don't think that's it...I tried other games with the same results. 

I got the screen full by using the stretch settings in the MAME menu.  Can I make those permanent as a workaround?

The setting in MAME probably is already saving but being overridden by the launcher script.  Something has gone ary in the settings on your build and I'd like to figure it out and fix it.  Even if the setting in MAME wasn't overridden I'd like to know what has gone wrong to help the next person who may ask.

Please try booting up with keyboard plugged into the Pi and then exiting the menus with 'f4', then 'f4' to exit the service menu to the command line.  Press 'ctrl'+'win'+'left_arrow' if the edges of the terminal run off the screen (it'l likely scale itself for low res, I'll fix this in a leter release).  Now try running the command:

mame279 openice

Exit the game straight away, I'm interested in the first line that is output by the script.  Below the first line will be some errors reported by the script and a segfault from when you quit the game, ignore them, only interested in the first line it responds with (on my test it was 640x480 - the resolution the script thinks the system is in).  If you like take a photo of the output and post it or just write what it said.  Once finshed type

sudo reboot

to reboot to the game selection menu, OR type

sudo poweroff

to shutdown the Pi.

We'll figure it out one way or another.... sorry for the hassle.

How should I exit the game?  Is there a key command for that?

either 'esc' on keyboard or long holding the start button (about 3 seconds) should exit the game.

1280x1024

well that's really weird.  High res mode should be 640x480... no idea why/how you got into 1024p but the launcher(s) will be getting it wrong at that res as it doesn't have any handling for it.

Did you do anything other than the highres.txt file method of setup?  Something unexpected has happened...
